Does this help? It's the instructions for the Phantom QD Flash Hider mount (not sure what mount you have).

308.pdf (installation instructions)

It looks like 0.625-24 UNEF-3A -- is that the thread class? I have to admit that I had to look up what most of it meant.

I threaded the barrel for my AR-10T and just set the lathe up for 24 threads per inch and threaded until it (I have the QD Flash Hider mount) fit well. Pretty much like I do barrels.

The threads are class 3A. Just like it states on the print.
